Pop Up Camper or lightweight to match 2500 6.4 ram

I have a hallmark (see sig) and love it. If I had this truck when I got the camper it would have been a Guanella.
That said, outfitter, Northstar were also contenders. The west coast campers (four wheel, ATC, etc) are also good possibilities and more plentiful where you are. Wander the West is a good reference for those. It all comes down to what you want.
